LIGHT DETECTION AND RANGING APPARATUS

摘要

A laser measuring device is provided to maintain a high light receiving efficiency by performing wavelength lights more than two kinds. A laser measuring device(100) includes a first light emitting part(121) and a second light emitting part(122). The first light emitting part lights a light of a first wavelength. The second light emitting part lights a light of a second wavelength, and is vertically positioned to the first light emitting part. An optical mirror transmits one light among the light of the first wavelength and the light of the second wavelength, and reflects the other light. One-band pass filter transmits a light of the first wavelength. A second band pass filter(152) transmits a light of the second wavelength. A light receiving part(130) receives a light irradiated through one among a first band pass filter and the second band pass filter. A control part activates at least one among the first light emitting part and the second light emitting part.
